STOP Djvu Decryption
In order to decrypt some of your files, we need some encrypted files and their originals.
Specifically, these file pairs need to meet the following requirements:
- • Must be the same file before and after encryption[1]
- • Must be a different file pair per file type you wish to decrypt[2]
- • Each file must be larger than 150KB
[1] E.g. files you downloaded from the Internet that were encrypted, documents sent via email, default wallpapers shipped with Windows, a copy from a flash drive, etc.
[2] For example: to decrypt PNG files, we need an encrypted PNG file and its original. Additional conditions may apply, depending on the file format.
Notice: this service does not support the "New" variants that use RSA encryption.
If your files were encrypted after August 2019, chances are it is the "New" version.
Frequent Questions
- What if my files are too big to upload?
- Please contact our support team, and we will be able to assist you with an alternative method.
- What will you do with the files I upload?
- User privacy is a major concern for us. We will only use the files provided to us in order to attempt to provide a way of decrypting some of your files. Once this has been done, the files are immediately deleted from our servers. No personal information is stored.

- Your files were likely encrypted by the "New" variant that uses RSA encryption, and cannot be decrypted at this time.
However, we recommend trying the decryptor as-is on your files, as some files might be decryptable if they were encrypted by an offline key that we have.
